StorNext M330 Metadata Appliance Hardware Guide
b Navigate to the StorNext Products page for your appliance (on
the lefthand side of the CSWeb site, look for the appropriate
link under the StorNext Products section).
The first section of the page contains Downloads for the given
appliance.
c Scroll down to the Current Software section, and download
both firmware image files.
• Firmware upgrade installation files, which contain the .fw suffix,
must be uploaded to the system prior to beginning the upgrade
process. Uploading the firmware upgrade files in a network with
low latency should only take a matter of minutes. High network
latency in your environment can slow the upload of these files onto
the Metadata Appliance.
• When using the firmware upgrade process from the StorNext GUI,
the license for the system will be automatically applied to the
StorNext M330.
For StorNext 5 and Later Upgrades Only:
• The upgrade is applied to both nodes sequentially, beginning with
the secondary node. When the secondary node has completed its
upgrade, the system will failover from the primary to the secondary,
and begin upgrading the primary system. While the node firmware
upgrade is being applied, metadata operations are not interrupted.
However, if a metadata array firmware upgrade is required, the
downtime is approximately 30 minutes, since both nodes will need
to reboot after the FW update is applied. The StorNext GUI is
available on the node acting as primary during the upgrade of the
node acting as secondary.
• The secondary node of the MDC no longer requires an HA
conversion, since both nodes are left in the HA configuration.
• Storage Manager components no longer require a restart as part of
the firmware upgrade procedure.
For Upgrades Prior to StorNext 5 Only:
• Each StorNext firmware upgrade requires a reboot of both nodes. In
some cases, multiple reboots of the nodes are required. The
StorNext GUI is not available during reboots which can each take 30
minutes or longer per node. The GUI for the secondary node should
not be started during this process.
